Roman Khachatryan commented on FLINK-18796: ------------------------------------------- I'm not sure whether it's actually a problem, maybe there is some implicit memory fence after assignment. But if it *is* a problem I'm also not sure how does it manifest itself, as it does not necessarily fail the sink; and sink is not exactly-once. Which pattern do you mean? > FlinkKinesisProducer.backpressureLatch should be volatile > --------------------------------------------------------- > > Key: FLINK-18796 > URL: https://issues.apache.org/jira/browse/FLINK-18796 > Project: Flink > Issue Type: Bug > Components: Connectors / Kinesis > Affects Versions: 1.11.1 > Reporter: Roman Khachatryan > Assignee: Roman Khachatryan > Priority: Minor > Fix For: 1.12.0 > > > (confirm first) > > cc: [~rmetzger] -- This message was sent by Atlassian Jira (v8.3.4#803005)
